the crux as I see it is the little mantel-ly move at the start. there is a pin that you clip just before making this move. if you slip (and it's pretty well worn from all the traffic), you go crash back onto the pile. This is common Gunks knowledge from other posts I've read. There is no other pro midway into that move; you just have to make the move which, once you do, you're stood up and placing all the gear you want. The potential for injury makes it PG-13. Not an issue if you're solid on 5.7, but potential problem if you're not.
we're all living proof that nothing lasts
